I have a Billy Goat Industries Pro Seris KD Vacuum / vac for sale. It has a 5 HP Briggs & Stratton and has only been used 4 times by us and has the origional bag (it has a small hole at the top of the bag, about the size of a quarter that I fixed with duck tape. This does not affect the opperation at all.) and has the optional hose to pick up out of the flower beds on whereever the vac cannot reach. It has never been left outside in the weather and it starts easy on the first pull and runs very well with no problems. The model is #KD511IC.I do not have the owners books for it but they can be downloaded from the Billy Goat website. I would like to get $450 for it but feel free to make me an offer. I will traveling to Pittsburg and then to Chicago next week and could bring it with me if it would help someone out.
